Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product
reliability.
AC/DC Characteristics
Table 5: AC Specification type Out A.pecl Pins (CPUCLK)
Test Load Conditions: 100
, 15 pF.
Note 1: The pecl levels are standard 10 kHz positive ECL values as shown in the table above.
Note 2: Pin skew and Duty cycle are measured at the signal swing mid-point.
Note 3: The skew and duty cycle numbers reflect the recommended clock distribution method shown in Figure 2
